Abstract

The present invention relates to a panel packaging material for a collapsible cathode ray tube, and the present invention has a strong support stiffness as the outer wall is composed of a plurality of layers (three and four layers) so that heavy large panels can be stacked without using steel pins. The strength of the lower plate and bearing wall corrugated board of the main body and the strength of the outer wall corrugated board can be applied differently, so that the corrugated paper of appropriate strength can be used and the requirements of the corrugated paper can be minimized. The lower part of the outer surface of the packaging material located at the top is wrapped and supported by less shaking when transporting the packaged product, and by simply placing the pad on the inner surface of the main body, the main body is simply configured and the main body is automatically disassembled when the pad is separated. It is a superficial packing material.

Description

Foldable cathode ray tube panel packaging {A knockdown packing case for the Panel of CRT}

The present invention relates to a packaging material used for storing and transporting a panel made of glass. The packaging material of the present invention is composed of a plurality of layers (3 layers and 4 layers) on the outer side, and has strong supporting rigidity, and the strength of the lower plate and the inner wall corrugated cardboard of the main body and the outer wall corrugated cardboard can be differently applied. Corrugated cardboard can be used and the required amount of corrugated cardboard can be minimized, and the lower part of the outer surface of the packaging material located at the top is supported by wrapping the upper four sides of the packaging material located at the bottom when laminated packaging, and there is less shaking when transporting the packaged product. The main body is simply configured by placing a pad on the inner surface of the container, and is a folding packaging material configured to automatically dismantle the body when the pad is separated.

In general, a cathode ray tube is made of glass and consists of a panel on which a fluorescent material is plotted on its inner surface and a funnel on which an electron gun is mounted. The panel and channel are individually fabricated in a glassware manufacturing plant and transferred to other producers or factories that produce cathode ray tubes and assembled with other components (shadow masks, guns, frames, etc.).

Such cathode ray tube panels and channels, especially large cathode ray tube panels and channels, are made of special glass and are very heavy and brittle. Therefore, the conventional packaging materials are injection molded packaging materials of expensive synthetic resin, such as patent registration number 320308 and registration number 378076, causing environmental pollution, and spend a lot of packaging costs with expensive packaging materials.

The folding packaging material of the present invention does not use steel pins in constructing the packaging material, and the outer surface is composed of a plurality of layers (three layers and four layers), so that the supporting rigidity is strong, and the strength of the lower plate and the inner wall corrugated cardboard of the main body The strength of corrugated cardboard and outer wall can be applied differently, so that corrugated cardboard of appropriate strength can be used, and the requirement of corrugated cardboard can be minimized. When the product is wrapped and supported, less shaking during transporting the product, the main body is simply configured by placing a pad on the inner surface of the main body, and is a folding packaging material configured to automatically dismantle the main body when the pad is separated.

In the folding packaging material consisting of the main body, the outer wall, the main body partition wall and the pad,

The lower inner plate 11 of the main body 11 is bent extending from the upper and lower outer edges to form a first width of the inner side walls 31, 51, and the inner wall flange portion of a predetermined length by extending from the left and right outer edges of the first inner wall ( 33 and 53, and diagonal curves 34 and 54 are inclined at an angle of 45 DEG from the lower left and right vertices of the lower plate 11 and the lower ends of both first inner wall flange portion bends to the upper inner surface of the first inner wall. Composed,

The second inner wall (21, 41) of the same width as the width of the first inner wall is formed extending from the left and right outer edge of the lower plate 11,

The first outer wall diagonal curves 35 and 55 are inclined at an angle of 45 DEG in the inner surface direction, and the first inner wall 31 and 51 have the same length and length, and the width of the first inner wall 31 and 51 is wide. First outer walls 32 and 52 which are a certain width larger than the width are formed,

The first outer walls 32 and 52 have the same width and width, and the second outer walls 22 and 42 having the same length as the second inner walls 21 and 41 are formed.

The first inner side wall has the same width and width, and the bottom surface is bent and extended to constitute a pair of partition walls 61 of a predetermined length, and is bent from the left and right outer edges of the partition wall 61 to have a predetermined length. The partition wall flange portion 62 is composed of a partition wall inclined at an angle of 45 ° from the center of the partition wall flange portion bending line 63 to the upper and lower outer cross-sectional directions of the partition wall 61 on the inner surface of the partition wall 61. A diagonal bend 64 is constructed,

The first and second diagonal wall curved lines 34 and 54 formed on the first inner wall 31 and 51 and the first outer wall diagonal curved lines 35 and 55 formed on the first outer wall 32 and 52 are bonded by adhesive. (2) The outer end face of the inner side walls (21, 41) and the outer long side end faces of the second outer walls (22, 42) are glued to each other, and the inner wall flange portions (33, 53) of the main body are connected to the second inner wall (41). The adhesive wall is adhered to the inner surface of, 42, and the partition wall flange portion 62 contacts the left and right outer end surfaces of the first inner wall flange portions 33 and 53 on the inner surface of the second inner wall 21 and 41. (61) is bonded with an adhesive so as to be located in the center of the inner surface of the lower plate 11,

 The pad long side wall 71 is in contact with the inner surface of the second inner side wall 21 and 41, the pad short side wall 72 is in contact with the inner surface of the partition wall 61, and the pad short side wall 72 of another pad is in the first inner side. The pad long side wall 71 is in contact with the pad long side wall 72 of the other pad, and the inner surface of the pad long side wall flange portion 73 and the inner surface of the pad short side wall flange portion 74. In contact with the inner surface of the lower plate 11, a plurality of (8) pads are placed on the inner surface of the lower plate 11 to constitute a folding packaging material of the present invention.

The folding packaging material of the present invention can be recycled again when the waste packaging material is used after use because it does not use steel pins in the composition of the packaging material, and the outer side of the packaging material is composed of multiple layers (three layers and four layers) to support the rigidity. This strong, the strength of the lower plate and inner wall corrugated cardboard of the main body and the strength of the outer wall corrugated cardboard can be applied differently, it is possible to use the corrugated cardboard of appropriate strength, and to minimize the amount of corrugated cardboard to reduce the manufacturing cost of the packaging material, The upper four sides of the packaging material located on the top of the outer surface of the packaging material located on the top of the lower end wrapped around the less vibration during transportation of the packaged product, by simply placing the pad (Pad) on the inner surface of the main body, the pad is separated The main body is automatically dismantled at the same time, reducing the packaging material assembly cost.
